“…Such networking models enable network users to share unused bandwidth with other users [1], [3] especially once users are out of coverage of their operators' networks. A spectrum sharing user (SSU) becomes a resource provider by acting as a dynamic access point and sharing temporally unused resources according to the incentives offered by network operators (NOs) [4], [5]. The concept of dynamic network architecture (DNA) [1] was proposed as an overlay model for pricing and incentives to develop user-centric networks where a user is at the same time A. S.

We develop and analyze a new user-centric networking model for ubiquitous spectrum sharing where every user can share and use the spectrum under uncertainty of their traffic models. In this concept, users when connected to the Internet (wired/wireless) can dynamically serve as access points for other users in their vicinity. For this reason, the concept is referred to as user-centric distributed spectrum sharing. Each user in spectrum sharing mode utilizes a part of its available spectrum for its own traffic and remaining part to share with users in spectrum demanding modes. The model is designed as an operator supervised double-Stackelberg game with network operators, access points, and users as main players. We study network reliability and latency of the system under uncertainty of users' traffic patterns. The numerical results show that the proposed model, depending on different settings, can significantly improve both profit and utility for network operators and users, respectively. Furthermore, network reliability is significantly improved depending on the network parameters for both users and operators.

Abstract-Dynamic network architecture (DNA) has emerged as a promising networking paradigm which establishes a low-cost ubiquitous network connectivity without the need for significant changes in software and hardware infrastructure. In this concept the major player in spectrum sharing process is the user itself hence the name user-centric spectrum sharing. Such user-based spectrum sharing concept is an opportunistic model due to the uncertainty in traffic patterns, which results in frequent interruption of the shared spectrum access. In this paper, end users (EUs) deal with this difficulty by choosing the least overloaded access points (APs) to have a longer access period without interruption. Moreover, we introduce spectrum outage probability parameter to investigate efficiency of spectrum sharing in DNA networks. The simulation results show that the network operators (NOs), dynamic access points (DAPs) and EUs significantly improve their utilities if they deploy a user-centric spectrum sharing model in DNA networks.
